Abstract
Orally administrable polymer-carrying units for expanding in a stomach of a mammal to fill a space in the stomach, the polymer-carrying units including: a carrier; a plurality of polymer molecules expandable in aqueous solutions, releasably coupled to the carrier; and means for selectively decoupling the polymer molecules from the carrier so that the polymer molecules and carrier are released in the stomach, are provided.
